CLEANING AND Specification of Letters Patent.

POLISHING COMPOUND.

Patented May '7, 1907.

T0 ti-Z whom it m/(11y concern:

Be it known that I, HENRY B. RADFORD, a citizen of the United States, residingat Chicago, in the county of (look and State of Illinois, have invented a certain new and useful improvement in Cleaning and Polishing Compounds, of which the following is a specificahon.

My invention relates to a compound to be used for cleaning and polishing the surface of steel, iron or other metals; and has for its object to make a compound which will not explode, if used in the vicinity or presence of llame from a fire, a light, or other source of combustion.

It is well known that in compounds or liquid preparations heretofore used in cleaning and polishing metal surfaces, more or less danger of explosion will be present owing to the fact that the compounds or preparations contain benzin or gasolene as the cleansing medium, and therefore such compounds or preparations are objectionable for general use. This objection to the liability of explosion is entirely overcome with the compound or preparation of the present ini yention.

. The compound of my present invention may be made in theform of powder, paste, emulsion or liquid. When made by the full formula given below it is in the form of a liquid; but when it is desired to make. it in the form of a powder, paste or emulsion the water is omitted in whole Oltll'l art.

Otherwise the general formula is app icable. When made in the form of a liquid the compound consists of neatsfoot oil, oxalic, acid, powdered pumice stone, powdered tripoli, oil of gaultheria and water, which ingredients are to be thoroughly and intimately mixed and I brought together so as to make" a homogeneous'mixture capable of use for cleaning" ounces powdered pumice stone, four ounces powdered trIpoh, one-eighth of an ounce of oil of gaultheria; and suflicient water to make one gallon of the mixture or compound.

The foregoing proportions will produce a compound or mixture in liquid form and having the requisite properties for cleaning and polishing metal surfaces but it is not my intention to confine the proportions of the various ingredients to those here given, the only requirement being that theproportions shall be such as to form a compound or mixture capable of being used to clean and polish metal surfaces.

The liquid compound or mixture can be prepared in the following manner: The oils are to be first intimately mixed with water andone or more of the other ingredients, ex-

cept the acid, after which asufiicient quantity of water is to be gradually added and the mixture stirred Well-during the adding thereof until the oil is minutely divided and suspended in the water, forming a creamy mass.

The acid is then added either in the form of crystals or powder, or a proportionate aqueous solution, after which enough water is sup lied to the compound or mixture to ma e one gallon. The resultant will be a homogeneous mixture of oils, acid and water in which the solids will settle when the mixture or compound is left standing.

The compound or mixture can be put up in suitable rece tacles capable of receiving and retaining t e samefor use, and in use the compound or mixture is to be applied ,to

the metal surface and rubbed over the surface to effect the cleaning and polishing of the surface, and no film or scum will be left on the surface as has heretofore been the case where oxalic acid, pumice stone and otheringredients have been used for theurpose of polishing or brightening metal su aces. The

lm or scum produced by the use of oxalic acid, pumice and other Ingredients will .be loosened by the oils so that such film or scum can be rubbed off or removed with a minimum of labor, and in addition a thin film of oil is spread over the cleaned or brightened plosive nature nor will it burn, and this result of being non-explosive .and non-inflanunable, is derived from the fact that while ,there is a small percent of oil present in the compound. or mixture, the oil is in'such a finely divided state and so intimately mixed with the water that flame or heat cannot cause the oil to burn or ignite, thus insuring perfect safety in the useof the compound or mixture in the presence of flame from a lire, a light or other i source of combustion.

The compound or mixture of the present invention possesses the qualities of effecting a uniform and perfect cleaning and polishing 3 or brightening of metal surfaces when applied thereto and subjected to the necessary rubbing, and in addition is not explosive or inflammable, so that its use is not attended with any danger even when used in.the pres- 5 ence of flame.

What I claim as new and desire to secure by Letters Patent is:

1. A compound for cleaning and polishing metal surfaces, consisting of neatsfoot oil,v

oxalic acid, powdered pumice stone, powdered tripoli and oil of gaultheria, substantially as described. a

2. A compound f or cleanin; and polishing metal surfaces, consisting of neatsfoot oil, oxalic acid, powdered pumice stone, powdered tripoli, oil of gaultheria, and water, substantialh' as described.

3. A compound for cleaning and polishing metal surfaces. consisting of sixteen ounces l of neatsfoot oil, four ounces oxalic acid, four ounces powdered pumice stone. four ounces powaered tripoli, one-eighth ounce oil of gaultheria, and sufficient water to make a gallon of the mixture or compound, substantial-ll as described.
